The AT17C512/010 and AT17LV512/010 (high-density AT17 Series) FPGA Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The high-density AT17 Series is packaged in the popular 20-pin PLCC. The high-density AT17 Series family uses a simple serial-access procedure to configure one or more FPGA devices. The high-density AT17 Series organization supplies enough memory to configure one or multiple smaller FPGAs. The user can select the polarity of the reset function by programming one EEPROM byte. The devices also support a write protection mode and a systemfriendly READY pin, which signifies a “good” power level to the device and can be used to ensure reliable system power-up.
